Advertising Age: Time Inc. has let InStyle publisher Nina Lawrence go less than six months after the company hired her. A successor has not been named. Steven DeLuca, who is publisher of InStyle sibling title Departures, is expected to serve as interim publisher in addition to his duties at Departures. A Time Inc. spokeswoman declined to elaborate on the reason for her exit. Her departure comes as Time Inc. readies its pitch to advertisers on Thursday as part of the annual digital NewFront presentations.
